You can have the property taxes on your home reduced if you are a disabled veteran. The amount of the reduction depends on your combined disposable income, the value of your residence and your local levy rates. Your combined disposable income has to be at or below Income Threshold 3, which is set from the median household income of the county your property is in, so the ceiling differs from county to county.
Apply through the county assessor where your property is located, not the state. Send the assessor the Senior Citizen and People with Disabilities Exemption from Real Property Taxes application, a Combined Disposable Income Worksheet, and your VA Benefit Summary Letter or a DOR Proof of Disability Statement. Your county assessor is also the office that can tell you how large your reduction will be.
